To ctZZ whom, it may concern,.- secured to the car-body by bolts or screws o o Be it known that we, FRANK R.

On the dead-wood pyprotected by the buf- 55 United States, have invented a certain new fer-plate q, are mounted two similar oppoand useful Improvement in Oar-Oouplings,of sitely-disposed upright brackets b b, secured which the following is a specification. by bolts e and having in their upper ends Ourinvention has relation toimprovements journal-bearings in which is fitted a roundro in car-couplers of the Janney type or comheaded bolt c, retained at its opposite end by 6o monly recognized as vertical-plane couplers. a pin or key d, and on this bolt is mounted a The objects of our invention are to prevent bell-crank lever 0., having one arm provided the draw-head from being pulled out and fallat its outer end with a ring in which is seingon the track if it shall be detached or cured the lowerend of a chain Z and its other i5 broken from sudden shock incident to startarm projectingdownward and backward.

In a car-coupler of the kind specified, the combination with tyhe draw bar and head, and the coupling-pin, of a rocking lever pivoted between its ends in supports adjacent to the draw-bar, having one end flexibly connected with the coupling-pin, and its other resting adjacent to the draw-bar, and a post connected with the draw-bar and arranged to engage the free end of said lever When the draw-bar
